     * We might rewrite this the way those API:s stabilize. Browsers doesn't handle pasting

     * so we need to do lots of extra work to try to get to this clipboard data.
     *
     * Current implementation steps:
     *  1. On keydown with paste keys Ctrl+V or Shift+Insert create
     *     a paste bin element and move focus to that element.
     *  2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
     *  3. Check if the paste was successful if true, process the HTML.
     *  (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
